Professional Spanish translation for legal, marketing and e-commerce sectors
Request a Free QuoteSpanish is the fourth most spoken language in the world, with over 500 million speakers across 20 countries. For Portuguese, Spanish and Latin American companies, professional Spanish translation is essential for communicating with markets that represent enormous commercial potential.
M21Global offers translation from and into Spanish in all variants — European Spanish (Castilian), Latin American Spanish (Mexico, Colombia, Argentina) — with native translators and ISO 17100 certification. We guarantee accurate, natural and market-adapted translations.
M21Global's Spanish translation services cover all business and personal communication needs. From technical translation of manuals, product sheets and software documentation to legal translation of contracts, regulations and corporate documentation.
We also offer marketing and e-commerce content translation for Hispanic markets, financial translation of reports and banking documentation, and business translation of presentations, newsletters and internal communications.
Every project follows the TEP process audited according to ISO 17100: native translation, independent review and final check. For multilingual projects including Spanish, we coordinate teams through a dedicated project manager maintaining consistent terminology and style.
M21Global's Spanish translators are native speakers — from Spain, Mexico, Colombia, Argentina or other Hispanic countries — with higher education in translation or their field of specialisation. Each translator is selected for their mastery of both the regional variant and the subject matter.
For projects targeting the European Spanish market, we select translators from Spain. For Latin America, we choose native translators from the target country — Mexico, Colombia, Argentina, Chile — because vocabulary, register and convention differences are significant: a Spanish "ordenador" is a Mexican or Colombian "computador".
Our continuous evaluation programme monitors each translator's quality. Visit the Native Translators page to meet the team.
M21Global provides certified Spanish translation for documents requiring official recognition in Spain or Latin America: certificates, diplomas, powers of attorney, contracts, immigration documents and court documents.
Certification is performed by a lawyer, notary or sworn translator (traductor jurado), according to the entity and destination country's requirements. For Hague Convention signatory countries, we handle the Apostille. We always verify formal requirements before starting, for first-time acceptance.
The geographical and cultural proximity between Portugal and Spain makes certified Portuguese-Spanish translation one of the most requested services at M21Global. Our experience with this language pair is extensive and documented.
Our Spanish translation services focus on five sectors with high demand:
Legal: commercial contracts, corporate documentation, regulations, court documents and due diligence for Iberian and Latin American operations. Legal translation into Spanish requires mastery of two distinct legal systems (Iberian civil law vs. Latin American variants).
Marketing and Communications: websites, advertising campaigns, social media content and corporate brochures. Cultural adaptation (transcreation) is fundamental — what works in Madrid may not work in Mexico City.
E-commerce: product listings, return policies, FAQs and marketplace content for Amazon Spain and Latin American markets. Multilingual SEO included.
Tourism: hospitality websites, tourist guides, menus and promotional content for the Hispanic market — the largest tourist-emitting market for Portugal.
Energy: technical documentation for renewable energy projects, environmental reports and licensing documentation for Iberian and Latin American markets.

The price varies according to document type, volume, language pair, urgency and regional variant.
